The gusset is 6 cm! Black tote bag with a three-dimensional yellow logo. It was a gift, and I don't use it, so would anyone like it? It's a 30 x 34 cm tote bag, an eco-bag. The material is sturdy, so it can handle heavy documents, etc. ^_^ It can also be an accent to your fashion ^_^ - Color: Black - Design: Three-dimensional yellow logo, square, dice - Inside: Simple interior Thank you for looking. I plan to ship it folded.
